Multiple Choice

The use of ____ will eliminate the results of Aeolian vibration.

Aeolian vibration is wind-induced oscillation of overhead conductors that, over time, can cause fatigue and failure. The way to prevent or greatly reduce these vibrations is by using vibration dampers attached to the spans. These devices introduce a small mass–spring system that taps energy from the vibrating conductor and dissipates it as heat, lowering the vibration amplitude at the wind‑induced frequencies. By damping the motion, the conductor experiences far less cyclical stress, which protects the line from fatigue damage. Other items like insulators, ground wires, or cable ties don’t provide this tuned energy dissipation. Insulators are for electrical insulation and mounting strength rather than damping dynamic motion. Ground wires primarily serve grounding and structural roles, not vibration control. Cable ties are not designed for the heavy loads and dynamic energy of Aeolian vibration and won’t effectively damp the motion.
